碩士 === 高苑科技大學 === 電機工程研究所 === 101 === The thesis is on the study of a solar hydrogen fuel cell mild hybrid vehicle power systems. By the electric energy collected from roof photovoltaic cell, the hydrogen can be produced by electrolyzer to accumulate energy storage. In this way, the need of infrastructure for the hydrogen refilling can be alleviated. Moreover, by using this structure of fuel cell mild hybrid power, the cost for the required fuel cell module can be reduced. The hydrogen energy produced from the electrolyzer utilized solar energy can be fully benefited. Also, the threshold on using the hydrogen and fuel cell technology can be effectively relieved and the goal of promotion and cost down can be achieved. The topics investigated in the thesis include the structure analysis, comparisons on various types, and energy management strategies for hybrid power systems on electric vehicles. Then, the fuel cell mild hybrid power system for electric vehicle is explained. Finally, a prototype of mild hybrid power system with battery as main source and fuel cell as auxiliary source is designed and implemented to verify and demonstrate the operation of the investigated mid hybrid power systems.
